M5 extensions are tailored to VAST stylus systems. Their diversity unites the material (length 40 mm) and its unique processing: They are based on bending and torsion-resistant carbon fiber technology, which ranks higher than the metal solutions even in the lower price segment. With three available versions, ZEISS REACH CFX 1, CFX 3 and CFX 5, the extensions correspond to the accuracy level of the respective coordinate measuring machine.
